Thanks to funding from the Bristol Avon Catchment Partnership, BART has been busy on the upper Somerset Frome since October working on our Diffuse Pollution Sediment Pathways Project. Sediment entering watercourses can have a detrimental effect on aquatic ecology, including fish and invertebrates. This project has used predominantly field surveys to identify where sediment is entering watercourses in the upper Somerset Frome catchment and to determine the sources of this sediment.
The survey period of the project draws to a close at the end of March and we have so far visited 191 locations on the upper Somerset Frome looking for potential sediment pathways. Sediment pathways have been recorded at over 110 locations on the main river Frome and its tributaries including Redford Water, the Rodden Brook and the Marston Brook. At each location the source of the sediment pathway has been determined where possible and a diffuse pollution grade has been allocated to identify the severity of the pollution pathway. Photo 1 shows an example of sediment entering the Rodden brook via a pipe during a wet weather event.
The most common, and sometimes very severe pollution pathways seen as part of this project have included poaching and trampling by cattle and horses (photo 2), muddy farm tracks, gateways and yards, maize grown to the edge of watercourses with very little buffer zone (photo 3), discharging pipes and road run off. The most severe pollution pathways have been re-visited during or shortly after heavy rain to collect further evidence.
Alongside the field surveys the Somerset Frome project included a public engagement campaign to increase local awareness of the issues surrounding erosion risk and diffuse pollution and to build stronger relationships with the landowners surrounding the river Frome. As part of this work a farmers’ lunch was held on 9th March 2017 in the upper Frome area. This lunch brought together local farmers, BART and Farming and Wildlife Advisory Group (FWAG) to discuss sediment pathway issues in the catchment and to encourage partnership work in the future.
Thank you to all interested individuals and organisations who have been involved in the project and sent in information to help us prioritise areas to visit. This work will be written up in April and the final report will include a diffuse pollution grade map and recommendations for future work so watch this space!
Thanks to funding from Big Lottery Fund‘s Awards for All programme, BART are pleased to announce that we will be running 4 new Riverfly Partnership training sessions. These one day sessions will provide participants with the skills needed to monitor aquatic invertebrates on a monthly basis as indicators of water quality. More information available here: http://www.bristolavonriverstrust.org/what-we-do/riverfly_monitoring/
All sessions are free, will run from 10am-4pm and will be filled up on a first come, first served basis.
– Lacock, Wiltshire: 28th April
– Batheaston, Bath: 11th May
– Freshford, Somerset: 20th May
– Chew Magna, Somerset: 25th May
If you are interested in attending a session, please email email@example.com
This #WorldWetlandsDay, some of the BART Team will be spending the day at Steart Marshes in Somerset continuing a vitally important project to monitor population levels of the European eel in this important wetland. This 2 week project, led by Westcountry Rivers Trust and funded by the Environment Agency, will assess how the eel use the Steart as important feeding zones, life habitats or as part of their migratory route.
Opened in 2014, Steart Marshes is managed by the Wildfowl and Wetland Trust and the Environment Agency and has been labelled as ‘a wild, wetland landscape for the future that helps people and wildlife adapt to climate change.’ Rising sea levels are predicted to completely flood thousands of hectares of saltmarsh and mudflats over the next 50 years. At some places, such as Steart Marshes, it is possible to realign the coastline, allowing vital new saltmarsh to form. As with all wetlands, the area provides habitat for a rich mix of wetland wildlife including otters, egrets, owls waders and wildfowl and its creeks are a nursery for the fry of important fish stocks. Not only this, but the habitat is a vital carbon storage area, absorbing tonnes of climate-polluting carbon as it matures.
We will update on the success of the project as it unfolds but we are pleased to have found the first evidence of eels using 2 different habitats within the site so far. We were joined in these findings by a familiar face from TV – Hugh Fearnley-Whittingstall, who came to learn more about Westcountry Rivers Trusts and BART’s conservation and research efforts. We look forward to seeing the plight of the eel on our screens in 2018 as part of Hugh’s new series exploring the Westcountry!
Thanks to funding from the Bristol Avon Catchment Partnership, BART will be working with 8 Riverfly monitors, 5 community groups, 5 schools and 5 farmers to monitor chemical water quality in their local rivers throughout the catchment over the next year.
This monitoring is testing for phosphates and nitrates with the global research project Freshwater Watch. Although naturally occurring in our rivers, concentrations of these elements can be increased by both agricultural and urban run-off and can lead to harmful algal blooms which strip waterbodies of oxygen and result in fish kills. Some of you may already have conducted Freshwater Watch monitoring as part of the hugely successful WaterBlitz 2016 event but this is a further opportunity for people to monitor phosphates, nitrates and turbidity in their local river. This biological and chemical monitoring will provide invaluable data to pick up local issues and aid us in directing future conservation work to improve our rivers.
Details on how to sign up will be released shortly but for now you can register your interest by signing up to the newsletter here.
This project is funded by the Environment Agency as a continuation of the Bristol Frome Pollution Project completed last year on behalf of the Bristol Avon Catchment Partnership. The aim is to maintain focus on improvements within the Bristol Frome and it’s tributaries which will lead to improved ecological status.
This project will focus on two main areas:
- Farm advisory visits
- Follow up visits to previously visited farms
- An inventory of future capital farm improvements
In-stream habitat improvements
- In stream habitat improvements by BART with local community assistance
- An investigation into improving the upper reaches of the river for the benefit of wild brown trout.
- An investigation of structures having an impounding effect on the river and those that are barriers to fish migration.
In-stream habitat works will take place from 20th-24th February and the 27th Feb-3rd March. If you are interested in volunteering, please get in touch with our Project Officer at firstname.lastname@example.org
